Abstract

Infragravity waves observed inside a harbor may consist of free waves not only propagated from offshore but also generated (released) at harbor entrance due to reduction of wave groups by diffraction and breaking. In this study, numerical simulations of both wind and infragravity wave transformations from offshore to harbor inside are conducted by using Boussinesq-type wave transformation models. In case that the remained free waves are not dominant in the wave field, the infragravity waves generated at harbor entrance can be reproduced in calculation of wave transformation for wind waves with considering nonlinear wave-wave interaction in their wave groups.
